. During Autumn 1990, the possible presence of microbial pathogens was investigated in two discrete populations of anaemic (rainbow trout fry syndrome; RTFS) rainbow trout fry. Dense pure culture growth of three types of yellow pigmentcd bacteria were recovered from moribund and dead animals on low nutrient media. The cultures were identified as coryneforms. Cytophaga columnaris and Janthinobacterium sp. All taxa induced clinical disease (with similarities to RTFS) in rainbow trout fry.
